This unique and versatile pen style otoscope exceeded my expectations. It did so by the ease in use with only a few minutes of orienting to the direction the ear scope was directed, for proper focusing. The comfortable and soft ear spoon was able to protect the ear canal without exceeding the depth of the ear canal. The device is versatile in that it can be used in the nose, throat, ear, navel or just about any orifice north or south for discovery and maintenance. Of note, my pet swallowed a rubber washer and with discovering it almost immediately before he had time to swallow it, I was able to view and scope his mouth to recover it. This pen like design is so convenient to charge by just a USB cable. This device will surely be one that I will not loan to any one if a writing instrument is required because of its uniqueness. I would highly recommend the device to others.
